A very (but not only) prophesy I see in the scriptures, far diff then what we been shown. A few diff outcomes, still sorting out. The beginning of this though, the first paragraph, seems to happen in ANY scenario, but the remainder not so clear at this point.
World leaders behind the scenes unite themselves, feeling and seeing through the scriptures that they must being in God's new government. Scriptures and things will be shown, very convincing, even contrary to what most have been taught, out of their own bibles. A choice will be had to be made by all. Those not prepared will be as those now who see it, which is right and which is the snare. They are the ones who have fallen asleep and the day catches them as a thief, so they realize they are naked and find they don't have the answers. Is good actually evil and evil actually good with what they had been taught.
Those who join will believe they are joining and supporting God and that all against his kingdom will have to die. That only true ones will be on the earth. An earthly cleansing, done with his earthly kingdom. Those not joined will be sought out, removed. On a whole, the entire earth will be in chaos. Mass food shortage. The dead from food shortage, from the armies, and those who did hide and not found, who don't die by sword or by famine, will die of pestilence. Death will be so widespread that they will never be buried.
Those who remain, and those who God allowed to remain, will rebuild. Earth will be scarce, cities overgrown. There will be a kingdom of God, and each year must a trip be made to receive the blessings of rainfall on the land in which one resides. Man shall still continue to age and die, but his years will be gaining as when men had lived long ago.
At the end of this era, nations will join themselves up, and seek to destroy this Kingdom of God. Then fire shall come out of heaven.
